Lyric discussion by IndieLover 

The "shirt tucked-in and shoes untied" phrase, repeated twice, is the one I kind of found most intriguing. Basically put, I think this is a gorgeous way of describing how these two people, in the face of one of life's most difficult situations, are attempting to put on a strong, smiling facade "tucked-in shirt," while actually, at their very core, being functionally "untied."

A tucked-in shirt is what? Completely aesthetic. There is no physical benefit or reason to have a shirt tucked in or not, - it's simply something you do to appear a little more "put together" to those around you.

An untied shoe, on the other hand, will probably be noticed after the shirt. This is something that's a little "below the radar." That being said, an untied shoe is more than simply an aesthetic problem, it's a functional one as well - you can very well fall down, and possibly hurt yourself from tripping on a shoelace. So to me, this phrase really, and I think purposefully, highlights the juxtaposition of appearances/reality, strength/weakness, maturity/age - all themes which kind of undercurrent through the song.

Any thoughts?

I didn't even think about that. But reading it, I completely agree. That's a really interesting way to think about, but I would believe that's what he was going for.

What a fantastic lyricist.

I'd realized that it meant not being functional - but I hadn't realized the putting on a facade of being put together. But you're exactly right. He's trying to put on a brave face, while completely falling apart...

@IndieLover I interpret the idea that one's shirt is tucked in yet their shoes are untied as someone either getting dressed or getting undressed. For the purpose of the subject of the song, I picture she was hastily getting dressed while leaving her house to avoid dealing with her father and his knowledge of the prior night. For the narrator, he was slowly undressing following some kind of service (it is a Sunday). Therefore, I picture each character in a different state of undressing/dressing which caters to their situation in a relatively fitting way.
